Text description provided by the architects. Bosques de las Lomas in Mexico City is conceived as a residential area in a wooded area. The clumsy architectural development has deforested the hills, transformed the forest into roofs, streets and concrete platforms with gardens, drained the rainwater into the municipal sewage system, reduced the natural water infiltration into the soil, preserved the native flora and fauna of the place. The property borders a federal reserve land, deforested due to the architectural development and the mismanagement of the authorities.
When we were invited to visit the BCH73 site, we found a pre-existing volcanic stone structure conceived as an enclosing stone wall leveling the upper part of the property, leaving half of the site 30 meters below the road, the neighbors , and their limits. The presence of the Federal Reserve in the East, the pre-existence of the retaining wall, its compliance with the regulations, as well as the program itself, helped us to take the decision of the Architectural Party, conceptualizing it as a translucent cantilevered block , surrounded by interesting current and future visuals (when the implemented ecological actions mature), with a clear division of the server and the served space.
Our traditional holistic way of working led us to the understanding of a cantilevered architectural-structural piece, with protected and ventilated facades, with energy conservation and generation actions, (achieving the Net-Zero factor), with water and ecological awareness for the environment , obtaining a calm and translucent interior space (programmatic requirements of the project), surrounded by light, natural air, with open and protected images, with a high quality of life inside.
The Net-Zero factor was achieved through the combined use of the Energy Foundation Piles supported by a heat pump (solar powered), good orientation, ventilation and environmental protection, as well as the adequate materiality of the structure. In the field of water actions, a biodigester system was installed that processes wastewater to irrigate the federal area, as well as the infiltration of rainwater into the subsoil to improve the conditions of flora and fauna in the poorly treated forest area.
As part of the reforestation, it was decided to plant endemic species such as the Tepozán, the Moctezuma pine (Ocote) and Avocado trees (fauna-specific), in addition to other tree-dwelling individuals naturally born on the pre-existing platform of the abandoned building. With great excitement we learned that a few days ago a Cacomixtle (threatened Mexican species) was found wandering through the Federal Zone. For the construction process, the prefabrication of the structure was implemented, which was launched 20 meters above the ravine without affecting the already battered forest area.
For whom: The house is conceived as a home for a retired professional couple. The rehabilitation of the ravine as a public and landscaped space responds to the physical and social environment. Why: The owners reached retirement age and decided to build a functional and quiet home that would meet their needs for their senior years.
